BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 234,549, dated November 16, 1880.

Application filed March 12, 1880.

To all whom it may concern:

Be it known that 1, WILLIAM DUKE, of Longtown, in the county of Panola and State of Mississippi, have invented a new and useful Improvement in Baling-Presses, of which the following is a specification.

Figure 1 is a sectional elevation of the improvement. Fig. 2 is a plan view of the lower grooved plate. Fig. 5 is a plan view of the I o friction-plate.

The object of this invention is to improve theconstruction of the baling-presses for which Letters Patent No. 100,687 were granted March 8, 1870, in such manner as to lessen the fric 1 tion, and thus allow the presses to be operated with a less expenditure of power.

The invention consists in constructing a retating baling-press with plates and rollers interposed between its friction -surfaces to diminish the friction when the press is operated,

as will be hereinafter fully described.

Similar letters of reference indicate corresponding parts.

A represents the frame of the press, which frame is provided with a baling-box, B, doors 0, and a platform B, as shown and described in Letters Patent No. 100,687. In the center of the base of the frame A is formed a screwhole, E, or to the said base-frame is attached 0 a nut to receive the screw F, the lower end of which has a square foot, G, formed upon or rigidly attached to it, to fit into the square cavity of the well H. The well H is formed of timbers placed in a hole in the ground, and

has a frame, I, attached to its upper end, to

rest upon the ground and receive the down ward pressure of the press.

To the upper end of the well H, or to the ground-frame I, is attached a plate or block, In the upper side of the plate or block J is formed a groove, K, which is made with vertical sides and an outwardly-inclined bottom, to receive the conical friction-rollers L, the inclination of 5 the bottom of the groove K being such that the upper side of the rollersL will be horizontal. Upon the rollers L rests a plate, M, at tached to the base of the frame A, and through which the screw F passes. If desired, the

(No model.)

plate M may be the faced lower side of the nut E when a nut is used.

The upper end or head of the screw F is made square to fit into a square recess in the lower side of the block or plate N, so as to hold the said block or plate N from turning. In the upper side of the block or plate N is formed a ring-groove, O, which is made with vertical sides and an outwardly-inclined bottom, and which is designed to receive the conical friction-rollers P. Upon the upper side of the rollers P rests the faced lower side, Q, of the follower R, or a plate attached to the said lower side of the follower B.

To the lower part of the frame A are attached one or more levers, S, to which the power may he applied; or the power may be applied to a gear-wheel or pulley, T, attached to the base of the frame A.

The press may be operated by hand, by horse-power, by steam-power, or by any other convenient power.

ith this construction, when the frame A is rotated, the screw F will be raised by the revolution of the nut E, forcing the follower R upward and compressing the material in the baling-box into a bale, the frame A being made sufficiently heavy to prevent it from moving up upon the screw F.

With this construction the friction from the rotation of the frame A will be very greatly reduced, thus removing the objection to the press described in Letters Patent No. 100,687.

If desired, the friction-rollers L I? may be made in spherical form, in which case the bottoms of the grooves K 0 should be horizontal.

I am aware that it is not new to use conical rolls on inclined faces, a follower-screw, or a well for the screw; but

What I claim is In a baling-press, the combination, with the follower-screw F G, of the well H, groundframe I, having apertured block J, with inclined groove K, the conical friction-rolls L, and the plate M, as shown and described.

WILLIAM DUKE.
